Check For Tkinter Events Globally (across Os)

I trying to make an application with a pop-up menu - when I type SPACE-R_ALT on my keyboard, globally across the OS (Windows in my case). When that happens, I want to pop-up a wind

Solution 1:

I figured it out with Furas's help - with Pyhook I can wait for events globally, and then tie in the event with tkinter events.
